Net Framework Based On Web Services-based Systems Research And Applications

With the development of computer technology, Internet and information processing technology widely adopted in various fields, Modern enterprises are faced with increasingly complex systems, and using more and more application systems. These application systems may be using different development tools, different language development, even running on different operating platforms, this forms many"information island".It is necessary for users to share the information and exchange data in these "islands of information". This has contributed to the rapid development of using service-oriented architecture technology to build Web-oriented application framework. MianYan "Environmental monitoring emergency command system" is one of the systems based on this line of thinking.This discussion expatiates the essential of the Microsoft.NET technology, multi-tier architecture, service-oriented architecture by researching multi technologies included. Then, it analyzes the current situation of Mianyang city environment protection office's information construction, and proposes this system construction principle and essential strategy in the base of the project background of Mianyang"Environment monitoringe mergency command system'. According to the user'demand with logarithm, function, performance and so on, it analysizes system application structure, work process modle, spot scheduler model, use case model and core class model. At the last, in the base of analyzing user'demand, it designs system's architect, function module, data and database, and expatiates the secure invoking technology of web services. Finally, implements Mianyang city's project construct of"environment monitor mergency command system".The research of issue, contributes to building Web Services applications system with .NET framework in the environmental protection industry as a pioneer, providing reference for environmental industry construction. In the process of project construction, this paper also proposes a lot of valuable building strategy that can be a guide to incoming construction of this area.
